[Petra/AI] Handle permadeaths for heroes hotfix

caused by a79a47effe and de3ed2cd19 petra will be blocked by not being
able to train hero again as she does not do rotations.
add check for matchlimits reached for permadeaths
more propper solution to handle training with numbers greater than 1
will be needed in the future.
